Carbon-vanadium nanocomposites were prepared by sol–gel route after incorporating vanadium pentoxide nanopowder in carbon matrix based on resorcinol–formaldehyde xerogel, followed by thermal treatment. The resulting samples were characterized by

Herein we report results from quantum chemical calculations on a large series of pyrone-like model compounds which are relevant for carbon basicity. In consonance with previous work (Carbon 1999, 37, 1002), pyrone-like functionalities at the edge of

Changes in crystal strain and crystallite orientation of three varieties of PBO fibre (namely PBO AS, HM and HM+) have been investigated during deformation from the analysis of diffraction patterns obtained across single filaments, using a synchrotro

In this work, a Spanish semianthracite was graphitized at temperatures ≥2400 °C. The aim of this research was to study the influence of the temperature on the evolution of the structural order of the graphitic materials obtained. Crystalline param

This series of papers covers several aspects related to the influence of external stresses on the crystalline microstructure of rigid-rod polymer-based fibres. For the study, the main three fibres of this type have been selected, namely poly( p -phen
